WATERPROOF pH METERS
CP-101, CP-102, CP-103, CP-104

Despite their small size, these pocket-sized, waterproof pH Meters are as accurate as lab meters and include such advanced features as automatic temperature compensation and replaceable electrodes. They meet the requirements expected of high-quality professional instruments.
Meters CP-101, CP-102, CP-103 are designed for taking measurements in clear water and water with low deposits content. Model CP-104 isdesigned for taking measurements in waters with deposits, sewage and soil.

Thanks to the newest generation microcontroller they are highly accurate and the readings are very stable and repeatable. All of the meters have automatic temperature compensation. Their waterproof casings allow these instruments to make measurements in extremely difficult conditions. The meters can be completely immersed in water. They all have two point automatic calibration, with automatic three buffer detection (4pH; 7pH; 9pH). All the meters are battery powered and have been designed to provide the longest work time possible.
In the CP-101, CP-102 and CP-103 meters, special gel electrodes are used. This allows measurements to be made without the necessity of soaking the electrodes in water or KCl. The electrodes are mounted in special plastic heads, which lowers the risk of breaking the electrodes.
The CP-104 uses replaceable 12 cm electrodes in plastic cover. They are equipped with a special ELMETRON connector to join them with the meter. Depending on your requirements, a special electrode for soil or sewage may be ordered. The electrodes for sewage can have their electrolyte refilled. The pH meter CP-104 also comes in special carrying case.
The warranty for the meter is 24 months (for the electrodes 12 months).

WATERPROOF CONDUCTIVITY AND SALINITY METERS
CC-101, CC-102 AND CC-103

This are a battery operated, pocket-sized, water-proof meter with the accuracy of a laboratory meter. It has three automatically switched ranges. Thanks to the newest generation microcontroller the readings are accurate, stable and repeatable.
CC-101 and CC-102 allow measurements of conductivity and temperature. They have three ranges switched automatically (autorange) They have also an automatic temperature compensation.
CC-101 counts the result displayed on the LCD to 25 0C and
CC-102 to 20 0C.
CC-103 enables measurements in g/l (ppt) counted in NaCl and temperature. Usually salinity meters count the conductivity into salinity in linear way. In this case it is taken that 2 mS/cm = 1 g/l NaCl. Such a simplification brings errors, because the dependence of salinity on conductivity isn't linear. In CC-103 thanks to microcontroller the curve of dependence between salinity and conductivity could be entered, what has lowered the mistake which increases with growth of the concentration.
All of the meters have an automatic temperature compensation. The meter's waterproof housing allows it to be used even after complete immersion in water. Stainless steel electrodes are built into a plastic replaceable head which is joined directly with the body of the meter, they enable measurements in liquids with deposits or oils. The meter is designed and built for long-lasting usage There are two kinds of calibration possible, either through the entry of the cell's constant K or using a freely chosen standard solution. All of the meters are battery powered and have a 24-month warranty.
